Trouble is in the corresponding for TPS40170.
Please let me know about two point below of TP40170.
※Vin: 24V, Vout: 12V, Iout: 7.3A
High side FET: CSD18503Q5A, Low side FET: CSD18531Q5A
-----------------------------------------------------------------------------------
①Attached waveform is High-side and Low-side FET switching.
I feel that dead time is narrow.
Is there way to expand deadtime for change external component?
(Customer is not want to change FET)
※Brown: Vin, Green: Low Gate, Blue: SW, Red: High Gate
②About TPS40170EVM-597, Low side FET's Gate is connect 1000pF capacitor(C20).
Is C20 capacitor have what effect?
I think that C20 part is increase Gate capacitance for Low-side FET, is it correct?
(Increase Gate capacitance ⇒ expand deadtime)
